Assistant landing device of a troubled airplane

Abstract

The assistant landing device of a troubled airplane of the present invention comprises a storing chamber under the front end of the airplane, which has a freely opened door, and a strengthen network the front end of which is connected with the airplane body. When the network is expanded from the storing chamber, it will not affect the descent of the front and back landing gears. A plurality of canopy packets arranged as an array are installed on the front and back sides of the network and may be opened by controlling so that a group of canopy packets are formed on the right and left sides of the body of the airplane so that the airplane may be descended slowly. Each of the canopy packets has a large and a small canopy packets and a gas container for being quickly charged with air so that the small canopy packet may be opened. A plurality of positioning parachutes are located on the distal end of the network, which may be opened by the applied force of the wind in order that the strengthen network will be expanded uniformly below the canopy body. The present invention has further provided a network cover the end portion of which has a decoupled parachute being controlled to expand in order that the network cover can be decoupled from the network.

What is claimed is: 
     
       1. An assistant landing device of a troubled airplane comprising: a storing chamber installed below a lower portion of a front body of an airplane, and the storing chamber having a door which may be opened freely;   a canopy packet means received within said storing chamber including:   a strengthen network which having a front end and two distal ends, the front end of which is connected with said storing chamber, said network is expandable and then attached close onto the lower portion of the airplane from the front body to the back of the airplane;   a plurality of canopy packets arranged as an array and connected on the strengthen network and each of the canopy packets has a plurality of canopies; and   positioning parachute means connected on two sides of each distal end of the strengthen network.   
     
     
       2. The assistant landing device of a troubled airplane as recited in claim 1, wherein the canopy packet means is enclosed by a network cover, and a distal end of the network cover has a decoupling parachute which is controlled to be opened for assisting the network cover to decouple with the canopy packet means. 
     
     
       3. The assistant landing device of a troubled airplane as recited in claim 1, wherein at least one canopy is included within each of said canopy packet, and the canopy has an inflatable envelop tube fixed on the canopy for assisting to open the canopy, and a gas container which is used to quickly charge air into said inflatable envelop tube. 
     
     
       4. The assistant landing device of a troubled airplane as recited in claim 1, wherein a connector is located within the storing chamber for being connected with the front end of said strengthen network. 
     
     
       5. The assistant landing device of a troubled airplane as recited in claim 1, wherein an inflatable envelop is installed on the strengthen network for assisting the network to fully open. 
     
     
       6. The assistant landing device of a troubled airplane as recited in claim 1, wherein said positioning parachute has an inflatable envelop tube for assisting the canopy to fully open and a gas container for quickly charging air into the inflatable envelop tube. 
     
     
       7. The assistant landing device of a troubled airplane as recited in claim 3, wherein the gas container is actuated by an electric signal. 
     
     
       8. The assistant landing device of a troubled airplane as recited in claim 6, wherein the gas container for quickly charging air into the decoupled parachute is actuated by an electric signal. 
     
     
       9. The assistant landing device of a troubled airplane as recited in claim 1, wherein said storing chamber is installed on a rear end of a front landing gear of an airplane. 
     
     
       10. The assistant landing device of a troubled airplane as recited in claim 1, wherein the strengthen network is shaped like a swallowtail. 
     
     
       11. The assistant landing device of a troubled airplane as recited in claim 1, wherein said plurality of canopy packets connected with said strengthen network are symmetric distributed on two sides of the strengthen network. 
     
     
       12. The assistant landing device of a troubled airplane as recited in claim 1, wherein said storing chamber is installed above a receiving chamber of the front landing gear.
